使用自动测试找不到命令/使用'bundle install'安装缺少的gem二进制文件

Question

我对RoR完全不熟悉.我正在关注Michael Hartl的书.我无法进行自动测试.请建议出现问题的原因和解决方法.

当我在Rails项目目录中的命令行运行'autotest'时,我得到以下信息:

-bash: autotest: command not found

当我运行'bundle exec autotest'时,我得到以下信息:

 bundler: command not found: autotest
 Install missing gem binaries with `bundle install'

这是Gemfile

source 'http://rubygems.org'

gem 'rails', '3.0.3'
gem 'sqlite3-ruby', :require => 'sqlite3'

group :development do
gem 'autotest'
gem 'rspec-rails', '2.4.1' 
end

group :test do
gem 'rspec', '2.4.0'
gem 'webrat', '0.7.1'
end

这是'宝石列表'的输出

Answer 1

bundle install --binstubs将捆绑包中的所有可执行文件安装到项目的本地bin目录中(请参阅http://gembundler.com/),然后就可以运行了./bin/autotest.

Answer 2

只需重新启动终端选项卡,然后重试.那应该解决它.
